Pulled the truck into the garage and put the truck into park. Turned the vehicle off and the vehicle did not register as it was in park but rather seemed to be in neutral. The truck began to roll backwards. I placed my foot on the brake pedal to stop the vehicle and moved the gear shifter to ensure it was indeed in park, it was in park. I turned the vehicle back on and confirmed that the truck was displaying P (park) on the instrument panel.

I purchased a 2014 Silverado crew cab ltz Z71 on August 16. Almost immediately it began having issues with the safety systems that were extra modules on this vehicle. Parking assist sensors do not work consistently, lane departure warning system fails to initialize or operate consistently and downhill grade breaking system fails to initialize or operate consistently, forward collision warning system fails to initialize and operate consistently. (I have photographs of the safety features failing). In addition, the heated/cooled seats (driver side) overheats with driver weighing 280 lbs - causing rear vent /exhaust covers to separate from the seat. Seat gets very hot- passengers in back of vehicle complain about extreme heat (again photographed failures) failures with safety system functionality are described by multiple owners of the same model truck (ltz) that I purchased. Same problems are described throughout this thread www.GM-trucks.com/forums/topic/152662-any-new-2014-Silverado-owners-having-issues-with-their-truck took to dealership- they kept for two days. Unable to reproduce problems. BCM and infotainment center updates failed to resolve. Heated/cooled seat overheating was not resolved- however, I duplicated it immediately upon departing from the dealership. Mileage is now 4300 miles with same problems. GM case [xxx] was opened on 9/9/13 and all issues remain unresolved after BCM update. Information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).
